First of all the plaque itself it cut from 1/4 inch BB Ply. I personally do not care for plaques that are much thicker then that. Steve Good sometimes suggests 1/2 inch to 3/4 inch pattern thickness. I often convert those to 1/8th inch and then I usually cut 2 of them. He did suggest 1/4 inch for this one and 1/2 inch for the backer board. I also went with both of his suggestions on this plaque. Normally for me, if I am going to mail a plaque I always use 1/4 inch backer board material to keep the cost of shipping down. However I hand delivered this one so I decided on 1/2 inch. It is also BB Ply. I sprayed the backer board with black because I like the high contrast on my plaques so the finer cuts stand out best. I cut the pattern as it downloaded from Steve's site, which is approx. 8 inches. A hint for mailing this type of item … I will often shorten these items to about 7 1/2 inches, it I am going to be mailing them, so they will fit easily in a bubble envelope that is 8 X 10. . I don' t know if you ever use spiral blades but the inside of the chain I cut with a #1 spiral and it helped me to cut the chain in a very short time. I started with the chain and I was done the the inside part in about 15 minutes or less. Hope I answered all you questions. Feel free to ask me about anything, any time. I like to help others whenever I can
